Sokar - Another SR20 Rebuild
Posted: Sun Aug 17, 2008 9:13 pm
Well we didnt pull my motor out of my sx just so VC could run his motor in, mine was due for a rebuild aswell, here are some low quality cellphone pics of the progress 
A very very dirty block, there are a few oil and powersteering leaks that are going to be fixed
Bores look fine, but the block will be re-sleeved to make room for some forged items.
Upskirt shot
The head, I was very very sad to disassemble the head, it was the quietest SR head I've ever heard (lifter and cam noise) and I hope it will stay quiet after the rebuild
More head shots
Shot of the highport inlet ports
Gonna need a new clutch, this one is poked... Also one of the "local" items, I think I might try the route Phinx went
Another item to upgrade, the throttle body
Measures between 40 - 50mm across, will check once I strip it off the intake
And now, the reason for the rebuild, this is a relatively new looking bearing, the lead coating still intact
This is a more used bearing, bits of the copper poking through
This is a F*#ed bearing, with the lead gone and the copper polished, my cyl 1 and 2 bigends had spun in the conrod. The bearings we pulled out are already 0.25 oversized, so I really hope the crank etc is still usable.
Here is a summary of the bearings, this isnt all of them, some are still in the tub with all the engine bits, notice the worn thrust bearing aswell, I have no faith in whoever built this motor before...
There you go, This week I will get the parts of to the engineers to check the damage and start ordering parts!
Grocery List:
Forged pistons
ARP headbolts
ARP Mains
ACL bearings (probably duraglide because of the oversize)
Cosworth MLS Headgasket
New Oilpump
New Clutch
Active Sump
Will post some pics of the crank as well as the pistons tomorrow.
